Purchased from: Butler Performance Inc.

My current project is a '76 Trans Am 461/TH400/3:24 Posi car. When I bought the car,the factory Shaker was in the trunk,but no drop base.After searching high and low for an affordable base so I could get the Shaker back on,I checked Butler and found this one. I ordered it and couldn't be happier.The fit was exact.It was easy to install and the in-scoop air filter plate that is included is very nice. I'm running an Edelbrock Performer dual plane intake with an Edelbrock AVS 750 carb.The only mod I had to make was getting a 90 degree/banjo-style fuel line instead of using the straight-in fitting supplied with the carb so the base would sit flat on the carb.Other than that,there are no issues with this base--even my factory scoop retaining ring fit perfectly.The best part is that the base is made from aluminum,so no worries ever of rust.The price is great too,when you compare Butler's custom aluminum base to a stamped steel OEM base(IF you can find one)--the Butler is less than half the cost of the cheapest OEM base I could locate.One last note: this base does NOT have an opening for an under-hood snorkel.All air comes in through the scoop at all times,so not only are you getting a nice base,you're also isolating the incoming air away from engine heat.Glad I bought one--Thanks Butler!!
